COMBINED WINDOW SASI-I AND VENTILATOR.

Specification of Letters Patent. Patented Mar. 29, 1910.

Application filed September 17, 1909. Serial No. 518,150.

To all whom it may concern:

Be it known that I, ALEXANDER L. STRAUS, a citizen of the United States,residing at Baltimore city, State of Maryland, have invented certain newand useful Improvements in a Combined \Vindow Sash and Ventilator, ofwhich the following is a speci fication.

This invention relates to ventilators for windows, and has for itsobject to provide a window ventilator of economical construction, foreither the top or bottom of a window, or both, which will be easy andeffective in operation and which may be readily adjusted to regulate theamount of ventilation and instantly secured in any adjusted position.

With this object in view, the invention consists in the improvedconstruction, arrangement and combination of parts of an improvedventilator, which will be hereinafter fully described and afterwardspecifically claimed.

In the accompanying drawing, Figure 1 represents an outside elevation ofa window to which ventilators have been applied at the top and bottom,made in accordance with my invention. Fig. 2 represents an insideelevation of a window to the bottom of which my invention has beenapplied. Fig. 3 represents a vertical sectional detail view on the planeof the broken line 3-3 of Fig. 2. Fig. 4 represents an enlarged detailview of part of the adjusting chain, and its pulley.

Like reference characters mark the same parts, wherever they occur inthe various figures of the drawing.

Referring specifically to the drawing, 5 indicates a portion of theoutsidewall of a house in which is secured a window frame 6, the walland frame being of any ordinary or usual construction and forming nopart of this invention.

7 and 8 represent, respectively, the upper and lower sashes of thewindow, and 9, any ordinary construction or design of inside trimming.

' In the lower sash of the window, 10 represents a bottom rail and 11the top rail which may be of the usual construction except that thebottom rail is not prepared as ordinarily to receive the lower ed e ofthe glass pane. At a suitable distance rom the bottom rail 10, anintermediate rail 12 is inserted in the sash 8 and the usual permanentglass pane 13 shown in Fig. 1, that the chain, may

is secured in the top rail 11, intermediate rail 12 and side rails 8.

At 14 is shown the upper rail and at 15, the lower rail of the frame ofthe ventilator ane 16, said frame being of the proper size to fill, whenclosed, the space between the intermediate rail 12 and the lower rail 10of the sash, the lower rail 15 being attached to the lower rail 10 ofthe sash by means of suitable hinges 17, the top rail 14 being beveledat 18 to fit a corresponding bevel 19 on the under sidev of theintermediate rail 12. A wire netting 20 or other suitable screen issecured in the opening of the sash between the lower portions of theside rails 8, the lower rail 10 and the intermediate rail 12. A bracket21 is secured on the in side of the intermediate rail 12 by screws 22,or other suitable means, in which is pivoted on apin 23 a pulley 24. Achain 25 is secured to the upper rail 14 of the ventilator frame andpasses around the pulley 24. This chain is of eculiar construction,consisting of short llllkS 26, and long links 27, at right angles toeach other.

The ventilator has been hereinbefore described as attached to the lowersash, and is illustrated in Fig. 2 as carried by the lower sash only. Itwill be obvious, however, as upper sash may be provided with anintermediate rail 28, and a screen 29, permanently secured between saidintermediate rail 29 and the upper rail '30, and that a hinged pane,such as described in connection with the lower sash, with its adjustingand securing bracket, pulley and be also attached to the upper sash, ifdesired.

Assuming'the ventilator frame to be lowered inwardly, as shown in Fig.3, by pulling the end of the chain, the upper end of the ventilatingframe may be drawn toward the intermediate rail 12 of the sash and bylettin up on the chain, the ventilator frame will rop to a lowerposition. By this means a smaller or larger opening will be provided forthe passage of air, while a corresponding adjustment of the upper end ofthe frame may be made to promote the escape of the warm air of the roomand thus create a ventilating draft, the occupantsof the room beingprotected from the draft by the ventilating pane 16.

Having adjusted the the desired inclination,

ventilator pane to one of the links 27 of the chain may be turnedcrosswise or which position it will preventthe drawing of the chainoutward by engaging upon the bracket 21. No manipulation of the link 27'is required to release the chain, it being only necessary to draw theupper part of the chain outward when the horizontal link,-

which has been acting as 'a stop pin, will be brought into line with theother links, and freely pass backward around'the pulley 24;.

The extreme simplicity and utility of the device will be obvious at aglance, and it will be further obvious that changes and variations maybe made in the specific construction of the various parts, withoutdeparting from the spirit and scope of the invention.

Having described the invention, what is claimed as new, is

The combination of a window sash, an

intermediate horizontal rail dividing it into two compartments, a paneof glass secured 1n one compartment, a screen secured in the othercompartment, a frame carrying a pane of glass and hinged to an outerrail of the sash in position to close or open the screen compartment,and a chain composed of alternately longand short links secured to thefree rail of the hinged frame and passing around the pulley, said longlinks acting in connection with said' pulley to form a look when turnedout of their normal position and being free to pass around said pulleywhen turned to their normal position.

In testimony whereof I afiix my signature in presence of two witnesses.

ALEXANDER L. STRAUS.
